CHURN.

SPECIFICATION forming part of Letters Patent No. 633,744, dated September 26, 1899.

Application filed March 30, 1899.

To all whom it may concern:

Be it known that 1, AUGUST REINHOLD AN- DERSON, a'citizen of the United States, residing at Cameron, in the county of Nez Perces and State of Idaho, have invented a new and useful Churn, of which the following is a specification.

The invention relates to improvements in churns.

The object of the present invention is to improve the construction of churns and to provide a simple and comparatively inexpensive one capable of rapidly eifecting the production of butter; and another object of the invention is to provide a double-dasher churn which may be readily adjusted to throw one of the dashers out of operation, so that the other dasher may be employed for collecting the butter after the operation of churning has been completed.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of a churn constructed in accordance with this invention. Fig. 2 is a vertical sectional view of the same, taken longitudinally of the operating-shaft, the gearing being in mesh. Fig. 3 is an enlarged sectional view 1 of the upper portion of the churn, showing the lower pinion out of engagement with the gear-wheel. Fig. l is a detail perspective view of one of the dashers. Fig. 5 is a detail view of the outer shaft and its pinion. 6 is a detailview of the swiveled support.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a bearing-frame mounted on a cover 2 of a churn-body 3 and consisting, preferably, of a' casting having a circular base portion 4, a horizontal top 5, and substantially vertical supporting portions 6 and 7, which are provided with horizontally-alin ed bearings for a shaft 8. The shaft 8 is provided at its outer end with a crank-handle 9, by means of which the churn is operated, and it has keyed or otherwise secured to its inner end a vertical bevel gear-wheel 10, which Serial No. 711,111. (No model.)

meshes with upper and lower bevel-pinions 11 and 12, connected, respectively, with outer and inner rotary dashers 13 and 14, which revolve in an opposite direction. The supports 6 and 7 of the bearing-frame are located at one side of the gearing, and the horizontal top 5 is supported at the opposite side of the gearing by inclined braces 15, converging upwardly, as clearly shown in Fig. 1 of the accompanying drawings.

The upper bevel-pinion is mounted on a Vertical dasher-shaft 16, extending from the top of the bearing-frame to the bottom of the outer dasher 13, with which it is connected, and the lower bevel-pinion is connected with the inner dasher by a short tubular concentric shaft 17, extending through the cover of the churn-body and capable of alimited vertical movement to arrange the lower bevelgear in mesh with the vertical gear-wheel, as illustrated in Figs. 1 and 2 of the accompanying drawings, and to'carry it out of such engagement, as illustrated in Fig. 3 of the accompanying drawings, to throw the inner dasher out of operation in order that the outer dasher may be rotated to cause the butter to collect in a mass around the inner dasher to facilitate the removal of the said butter.

The bearing-frame is provided at its top and bottom with bearings for the said shaft, and the short vertical movable shaft 17 hasa movable supporting device swiveled to it. This movable supporting device 18 consists of a horizontal top portion and depending arms or legs 19, adapted to engage the upper face of the cover to hold the lower pinion in mesh with the gear-wheel and capable of ex tending into perforations or sockets 20 of the said cover to permit the lower pinion to be lowered out of mesh with the gear-wheel. The supporting device 18 is preferably ar ranged inan annular groove formed between the top of the short tubular shaft and the lower face of the adjacent bevel-pinion. lVhen the lower bevel-pinion is in mesh with the gear-wheel, the depending arms or legs of the supporting device are preferably arranged in recesses 21 of the lower horizontal portion of the bearing-frame,the position of the supporting device being then at right angles to the an eccentrically-arranged perforation therein on the seat, which is slightly curved.

position occupied by it when the gearing is out of mesh, so that there is no liability of its accidentally working out of position.

The inner and outer dashers,which are substantially rectangular, as shown, consist of inclined sides or blades and horizontal top and bottom portions connecting the same, the blades or sides being disposed at an inclination in order to enable them to operate to greater advantage on the contents of the churn-body. The upper cross bar or portion of the outer dasher is provided with a circular opening 22, through which passes the short tubularshaft, and the lower connecting-bar of the outer dasher is provided with a rectangular opening to receive a squared portion 24 of the central shaft 16, which has its lower end threaded for the reception of a nut 25. The inner dasher is provided at its upper connecting portion with a rectangular eye 26 to receive a squared portion 27 of the short tubular shaft, and the lower connecting portion is provided with a circular eye to receive the central shaft. The dashers are detaehably secured to the shafts by the nut 25, and the squared portion of the short tubular shaft is of snfiicient length to permit such shaft to move vertically without becoming disengaged from the inner dasher.

The churn-body preferably consists of a stonejar; butit may of course be constructed of any other suitable material, and when constructed of stone it is provided with a resilient band composed of two substantially semicircular sections 30, connected at their adjacent ends by resilient ears 31, each consisting of a substantially U-shaped piece of springmetal having its ends flattened and riveted or otherwise secured to the ends of the sections of the band,and the said ears are rounded between their ends and pass through eyes of a bail 32. The bail 32, which is hinged to the ears, carries a centrally-arranged cam-lever 33, which engages a seat 34 of the top of the bearing-frame. The cam-lever, which is provided with a substantially circular head, has

to receive the bail. The cover of the churnbody is firmly locked in place by rotating the cam-lever on the bail after it has been placed The bearing-frame is provided at its substantially circular base with a curved inwardly-offset portion 35, arranged between the inclined braces and located oppositeasegmental opening 36 of the cover, which is provided around the outerportion of the opening with a lip 37, and apivoted strainer 3Sis arranged to coverthe opening. The strainer, which is segmental, is provided with a suitable grip or handle to enable it to be readily rotated to arrange it over the opening for enabling but termilk to be drained off, and the said strainer is also adapted to uncover the opening to permit water to be readily introduced into the churn for washing the parts.

The invention has the following ad vantages:

The churn, which is simple and comparatively inexpensive in construction, is capable of enabling the buttermilk to be drained off, and

it will permit the opening of the cover to be wholly uncovered, so that water may be introduced into the body. The dashers by being arranged as shown are adapted to cut up the butter and wash the same, and they also are capable of working the buttermilk out of the butter while the latter is in the churn.

' Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

lVhat is claimed :is

1. In a churn, the combination of inner and outer concentric shafts, the outer shaft being capable of a limited vertical movement, dashers connected with the shafts, upper and lower pinions mounted on the inner and outer shafts,a gear-wheel meshing with the pinions, and a supporting device swiveled to the outer shaft and holding the lower pinion in mesh with the gear-wheel, said supporting device being arranged to lower the outer shaft to carry the lower pinion out of mesh with the gear-wheel and thereby throw one of the dashers out of operation, substantially as described.

2. In a churn, the combination of a cover provided with openings or sockets, inner and outer concentric shafts, the outer shaft being capable of a limited vertical movement, dash ers mounted on said shafts, upper and lower pinions fixed to the inner and outer shafts, a gear-wheel meshing with the pinions, and a supporting device swiveled to the outer shaft and provided with legs adapted to support the lower pinion in an elevated position and capable of being arranged in said openings or sockets to lower the bottom pinion and carry the same out of mesh with the gear-wheel, substantially as described.

3. In a churn, the combination with a support having openings or sockets, inner and IIO outer concentric shafts, one of the shafts bej perforations or sockets substantially as described.

4. In a churn, the combination with a body and a cover, of a bearing-frame, a resilient band composed of sections encircling the body, resilient ears connecting the sections of the band, a bail hinged to the resilient ears, and a cam carried by the bail and engaging the bearing-frame, whereby the latter is fastened to the ch urn-body, substantially as described.

5. In a churn, the combination of a cover having an opening and provided with a lip,

I and a strainer pivoted to the cover and arranged to swing over the opening and adapted to be turned from over the same, substantially as described.
